Coinbase message are messages that only miners can embed in the blockchain.
As such most of them tend to be boring ads for mining pools, but there are a few exceptions, especially in the early days.
The Horrible Horrendous Terrible Tremendous Mining Pool inscribed a few cute Coinbase messages during their operation in 2012-2013.
Many of their messages also mention SockThing, which was part of their mining infrastructure:
Starting from their very first ASCII transaction on block 197602 (2012-09-07), there is what seems to be a poem spread across several transactions. Some of the lines are repeated, presumably because they didn't update the current line to a new line and so mined the same thing multiple times:
I am a pretty princess
covered in mud and blood
water with stuff in it
like everything else that wiggles or jiggles
screaming might not be your waY
see no reason to operate otherwise since
came into the world naked, wet and screaming
but silence will never be mine
until I am dead
but the smell will also give that away
gather all my things
load them in a big boat
airlift that to Kansas
and light it on fire
drop it from 7,000 feet
then railgun my corpse straight down
The sentences are not very coherent together, perhaps this is because lines were chosen by different miners one at a time.

no doubt initials of 4 Chinesepeople. A blood brother oath comes to mind, akin to the Oath of the Peach Garden. Will these four be the ones to take down the evil dictator Xi Jinping?
The very first message gives away the name of what we assume is a web-based upload system, "EW" being its advertisement signature added to every message.

Mycoplasma genitalium by Ciro Santilli 40 Updated 2025-07-16
Size: 300 x 600 nm
Has one of the smallest genomes known, and JCVI made a minimized strain with 473 genes: JCVI-syn3.0.
The reason why genitalium has such a small genome is that parasites tend to have smaller DNAs. So it must be highlighted that genitalium can only survive in highly enriched environments, it can't even make its own amino acids, which it normally obtains fromthe host cells! And because it cannot do cellular respiration, it very likely replicates slower than say E. Coli. It's easy to be small in such scenarios!
Power, Sex, Suicide by Nick Lane (2006) section "How to lose the cell wall without dying" page 184 has some related mentions puts it well very:
One group, the Mycoplasma, comprises mostly parasites, many of which live inside other cells. Mycoplasma cells are tiny, with very small genomes. M. genitalium, discovered in 1981, has the smallest known genome of any bacterial cell, encoding fewer than  genes. Despite its simplicity, it ranks among the most common of sexually transmitted diseases, producing symptoms similar to Chlamydia infection. It is so small (less than a third of a micron in diameter, or an order of magnitude smaller than most bacteria) that it must normally be viewed under the electron microscope; and difficulties culturing it meant its significance was not appreciated until the important advances in gene sequencing in the early 1990s. Like Rickettsia, Mycoplasma have lost virtually all the genes required for making nucleotides, amino acids, and so forth. Unlike Rickettsia, however, Mycoplasma have also lost all the genes for oxygen respiration, or indeed any other form of membrane respiration: they have no cytochromes, and so must rely on fermentation for energy.

Figure 1.
Saint Eligius by Petrus Christus
. Source. Off-chain image for illustration. Eligius pool is named after Saint Eligius, patron of goldsmiths and miners[ref]
These are some of the earliest inscriptions in the blockchain, and therefore extremelly visible.
Although the prayer verses appear contiguous in ASCII dumps, Eligius was not actually mining every block: it is just that in those early days, miners still hadn't started adding advertisement messages to every block, so only Eligius shows up and appears contiguous.
At some point, opponents noticed these messages, and started adding atheist mockery graffiti replies, which appear interspersed in ASCII dumps with the prayer.
The first prayer is the Latin version of the Divine Praises, a Catholic prayer composed in 1797 in Italian by Luigi Felici for the purpose of making reparation after saying or hearing sacrilege or blasphemy. Luke claims he was referring to anything in particular that came prior in the blockchain: twitter.com/LukeDashjr/status/1749182637569122434. There arent many earlier inscriptions at all to refer to in any case! The prayer and correspondong interrupts (in transaction outputs, not by other miners) ordered by block are:
  • 139690 (2011-08-05) prayer: "Eligius/Benedictus Deus. Benedictum Nomen Sanctum eius."
  • 139717 prayer: "Eligius/Benedictus Deus. Benedictum Nomen Sanctum eius.'
  • 139758 interruption: ***************************************************. This is not a Coinbase message: www.blockchain.com/explorer/transactions/btc/23befff6eea3dded0e34574af65c266c9398e7d7d9d07022bf1cd526c5cdbc94. This Bitcoin input script appears to spend a standard P2PKH output, but it first adds an extra value to the stack which contains the ***.
  • 139792 prayer: "Benedictus Iesus Christus, verus Deus et verus homo.'
  • 139831 prayer: "Benedictum Nomen Iesu.'
  • 139838 (2011-08-06) interruption: "I LIKE TURTLES" (tx 78eb16507b3d3df615e3b474e853db4667f4b11954ec6d918b1ded0fca7ad25a)
  • 138898 prayer: "Benedictum Cor eius sacratissimum."
  • 139904 prayer: "Benedictus Sanguis eius pretiosissimus."
  • 139921 prayer: "Benedictus Iesus in sanctissimo altaris Sacramento."
  • 139942 prayer: "Benedictus Sanctus Spiritus, Paraclitus."
  • 139954 interrupion: "aC-C-C-COMBO BREAKER" (tx 138c024a76df99ecafd2236d5429cf574b7778a3c6508bd83f116c832f3c6980)
  • 139960 prayer: "Benedictus Sanctus Spiritus, Paraclitus."
  • 139977 prayer: "Benedicta excelsa Mater Dei, Maria sanctissima."
  • 139990 (2011-08-06) prayer: "Benedicta sancta eius et immaculata Conceptio."
Then comes:
and various others + output message interruptions.
Then at last come the first miner message interruptions. Luke explained on Twitter[ref] that they were also made by Eligius pool, as there was a system in which contributors besides Luke could submit their own strings:
followed by more prayers and interruptions such as tx ec92d245822fa1ff862f3314b9102f36fe1eb8bc055865674c75323540aedef6:
FFS Luke-Jr leave the blockchain alone!
Oh, and God isn't real
The last Luke prayer appears to be on block 143822 (2011-09-03)
... the Lord of the harvest, that he send forth labourers into his harvest.
Then there is a bit of radio silence, until finally Slush Pool started self advertising for the first time on block 163970 (2012-01-26):
/P2SH/BIP16/slush/R,
They had been mining for a long time by then (December 2010 according to en.bitcoin.it/wiki/Slush_Pool), but this is when they decided to add a human readable ASCII message as well.
From then on, miner messages would be forever polluted with ads, and Luke's multi-miner message feat would never again be reproduced.
The non-obvious interruptions are all well known memes/anime references:

Myoglobin by Ciro Santilli 40 Updated 2025-07-16
From Wikipedia:
In humans, myoglobin is only found in the bloodstream after muscle injury.
These can be viewed at bitcoinstrings.com/blk00052.txt and are mostly commented on the "Wikileaks cablegate data" section of Hidden surprises in the Bitcoin blockchain by Ken Shirriff (2014).
Soon after block 229991 uploaded the Satoshi uploader, several interesting files were added to the blockchain using the uploader, and notably some containing content that might be illegal in certain countries, as a test to see if this type of content would make the Bitcoin blockchain illegal or not:
So basically, this was the first obviously illegal block attempt.
None of this content is particularly eye-popping for Ciro Santilli's slightly crazy freedom of speech standards, and as of 2021, the Bitcoin blockchain likely hasn't become illegal anywhere yet due to freedom of speech concerns.
Furthermore, it is likely much easier to find much worse illegal content by browsing any uncensored Onion service search engine for 2 minutes.
Ciro Santilli estimates that perhaps the uploader didn't upload child pornography, which is basically the apex of illegality of this era, because they were afraid that their identities would one day be found.
Bibliography:
All found so far are also reproduced at: asciiart.website/index.php?art=people/naked%20ladies therefore not blockchain original.
Some of the very first ASCII art present in the blockchain besides BitLen is porn. Surprising?
Rickrolling lyrics were mined several times into the blockchain.
The first currently known instance is as a link right during the prayer wars on block 142573 (2011-08-25) as the miner message:

Pinned article: Introduction to the OurBigBook Project

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.

  2. local editing: you can store all your personal knowledge base content locally in a plaintext markup format that can be edited locally and published either:
    This way you can be sure that even if OurBigBook.com were to go down one day (which we have no plans to do as it is quite cheap to host!), your content will still be perfectly readable as a static site.

    You can publish local OurBigBook lightweight markup files to either https://OurBigBook.com or as a static website
